7 Simple Tips for DIY Heating System Repair

The HVAC industry valuation was $7.17 billion in 2019.

An efficient house heating system saves energy costs and enhances comfort in the house. However, the systems are prone to both minor and major faults, mainly if you don’t observe regular maintenance.

The significant issues require the help of an experienced technician, but you can solve the minor problems without assistance.

This guide will discuss the simple DIY heating system repair tips you can readily handle before seeking professional help.

These tips can help you better understand the system and save you the costs of hiring an expert.

  1. Replacing the Thermostat Batteries

Every furnace heating system comes with an efficient thermostat. The thermostat heats the water or the surface as per the user’s needs. The modern thermostats come with indicator lights for low battery. Besides the light, some thermostats have audio alerts for low battery notifications.

Unless there is an underlying issue, you can replace your thermostat battery with ease. You will only need to carefully open the thermostat’s cover, remove the battery, and replace it with the new one. Ensure that the new battery is of the same size as the old one to avoid inconvenience. Also, don’t forget to close the front cover after installing it.

You may switch the heater on to see if the new battery is functioning well.

  1. Cleaning the Pipes and Ducts

It’s normal for the piping system to accumulate debris, sediment, and sludge. The buildups block the continuous flow of water in the systems and contribute to the bursting of the pipes. Ideally, you should inspect the pipes every month even when you don’t suspect a problem.

You might not remove all the pipes, but you can use a long cleaning brush to remove the dirt particles. You can also use the cleaning detergents mentioned on the user manuals to clean your heating system pipes.

If the clogs are many and the pipes are messy, do not attempt the self-cleaning because you might cause more problems. Contact your reputable heating system repair company to inspect the system and recommend an ideal solution.

  1. Changing the Filters

Old and worn out filters affect the general flow of water in the hot water system. They also affect the quality of the air of your HVAC system.

Changing the filters is an excellent way of increasing the efficiency of your furnace heating system.

If you suspect that they are no longer efficient, follow the steps below to change them:

  • Switch off the heating/furnace system
  • Turn off the thermostat too to prevent the loose debris from escaping through the duct
  • Locate the position of the filters
  • Measure the dimensions or the size of the filters so that you can buy the exact one
  • Insert the new filters carefully
  • Turn on the thermostat and test the efficiency of the new filters

Homeowners who can take care of this easy task of changing filters can save some costs and prevent system downtime.

  1. Oiling the Furnace

The furnace requires maximum lubrication for it to operate well. The regular lubrication also extends the life of the heating system. You need to oil the heating systems particularly in winter when they’re used the most.

Here is a simple process for oiling the furnace:

  • Turn off the primary power source
  • Detach the screws which enclose the furnace of the heating systems
  • Remove the bolts which surround the motor so that you can access the motor
  • Carefully remove the motor from the housing and add 2 to 3 oil drops of oil to the motor’s ports
  • Return then motor when done and activate the heating system

Watch the new performance and compare it to the previous performance. The system should operate more efficiently than how it was without the lubrication.

  1. Minimizing Excess Noise

It’s normal for your heating system to produce minimal noise. However, the sound shouldn’t be too much to obstruct you from your daily activities.

Here are the main types of sounds and what they could mean:

  • A popping sound implies that the ductwork is contracting or expanding
  • Rattling noises suggest that the panels are loose and you should tighten them
  • Squalling noises imply that the motor belts are worn out, and they need replacement
  • Drifting sounds means that the motor bears have an issue

Understand the type of noise coming out first before you attempt the repair. Also, switch off the furnace system first to prevent fire risk when replacing the motor bears.

Lubricate the system too because the noises could mean that there is too much friction in the system.

  1. Fixing Leaky Ductwork

Leaky ductwork is an invisible issue that causes visible problems. For instance, the leaky ducts blow cold air from the furnace instead of the usual warm air. The leaky ducts also contribute to the extreme water loss, mainly if you use the furnace to heat water. You can repair the leaky ductwork into two DIY friendly methods. You can either fix the particular leaky part or replace the entire duct.

Repairing would be the ideal option for the small leaks, while a replacement is a term solution for the significant leaks.

Consult a technician on the best solution if you are not sure of the ideal solution.

  1. Changing the Blower Fan

The fan is the central unit of the heating system. It is a big drum attached directly to the motor and the shaft of the furnace.  The fan becomes inefficient due to age, poor thermostat settings, or due to dirty filters. If the filters are clean and the thermostat settings are okay, replacing the fans would be the only suitable solution.

Follow these steps to remove the fans effectively:

  • Turn off the power
  • Remove the screw which encloses the motor and the fan unit
  • Carefully remove the fan and replace it with the newer one
  • Reassemble the system in the reverse order, and then switch on the system to test the efficiency of the new fans

Always remember to verify that there’s no electricity to the furnace as you disconnect the blower.
